- To all whom t may concern/."1

Be itknown that I', LUD. -`I-IoLLANix-Im'rz, acitizen o'ftheUnited States,`residing atOak Park7 in the `county ofvCook and btate of Illinois, have invented certain new and use-A ful Improvements in Buckle Slats for Con#- veyers, of which the following a Vfull, clear, and exact specification.y ,f'

My invention relatesto conveyers and.es;. `pecia'lly, to afbuckle' slat for conveyers.

vConveyers. or-,aprons used tocarry grain and like'material are usually provided with Cross slats and also with? longitudinal stra-ps, the strapsl of one portion 4of the conveyer having buckles attached thereto which l cooperate with lthe corresponding straps carried by -the otherendfof the conveyer. The

use of these slats sometimes gives risefto di'iiiculty in the mounting' ofthe, buckles'on the straps and this is more,particularlytrue when `the slats and strafpsareqelnployed Aon circular or quadrantal conveyers,since when usedfwith ythis ty-peof conveyer 'the slats converge at one side of the conveyer and diverge ,at the outer side;4 Because of the con'- verging-of the slats ,sufcient space for the mounting of the ybuckles between the slats is not provided.` v.

Another difficulty which has'been encoun-y tered is that of maintaining thefbuckles =on the different Straps'in alinem'er'itvv with s each other. across th'e'conveyer. f p

Having these difficulties in mind' the object yof'my.presentinvention is to provide a construction `whereby the space on; theIk apron is conserved and the buckles will beproperly alined. l

The object of the invention above stated is attained in the present embodiment by forming the buckles on one ot the cross slats of the conveyer.

One embodiment of the invention is illustrated in theaccompanying drawings, and in these drawings,y

Figure l shows in plan view a portion of a quadrantal conveyer equipped with my 1mproved buckle slat;

Fig. 2 is an enlarged view of a portion ot the conveyer shown in Fig. l;

F igt?, is a sectional view of the construction shown in Fig. 2; and

Fig. 4 is a cross sectional view on an enf larged scale, the view being taken through the buckle tongue and the cooperating slat portions.

,i In Fig. l Ihave illustrateda portion 0faquadrantal vconveyer 10. .having a ,fsei-iesf of slats 11 carried thereby, these slats radiating from thecenter of curvature of the conveyer,

.The conveyeris also providedl with a series of straps l2 conforming incurvatureto the curvature of theconveyer.

The .slats f 11 are provided with upstanding lugs 13A i which engage thegrain being, carried around by the conveyer. In the place` of the usual 'buckleslcarried by the straps l2, y,I havegsubstitutedI a 4buckle slat M which is .rigidly v secured to the conveyer yand vstraps-12,i'npa ilnanner hereinafter described, .and takes ythe yplace of one oflthe slats 1ldescribed; above.

The details ofthebuckle slatareshown in Figs. 2 to 4', and as. illustrated; therein` the slat 4is preferablyy formed .ofgsheet .metal and has laihorizontal.body portion 1-5, a vertical web portion 16 andarearwardly. extendingv substantiallyhorizontal flange portion 17. The body portion 15 ofthe slatis provided at spacedy intervalsithroughout fits length with a series of slots 18,theymaterial punched j out' lof thebody portion `to,--' for'm these slots being bent upwardlyandforwardly to form the strapengagingorfsupporting pjortion-19 which 4cooperates with the tongue, 2 0

of the buckle in holding the strap initsad@- justed' position. The-tongue; 20. of e'ach of 'the'.buckles is provided 'with 'atra-nsverse slot1i2l which isfen'gaged-by Iaforwardly and downwardly curyed.portion 22, the; latter port-ionbeing ormed-bypunching out a portion of the vertical web 16, this operation also forming a slot 23 in said web portion which registers with the slot 18 in the horizontal body-,portionof the slat.

As clearly shown in Fig. 4:, the tongue re'- taining portion or member 22 is `bent down.-

wardly into contact with the upper surface of the horizontal body portion 15 of the slat. They ends of the buckle slat are provided with flanges 24, the angeat the innerv end of the slat forming a bearing for the slat and contacting with the rimof a wheel 25 which guides the slats and oonveyer in the travel around the conveyer frollers, one of which is shown at 26.

The body portion of the conveyer 10 and the straps 12 Iare secured to the body portion 15 of the buckleslat by'means of a` member 27 having a flanged serrated pe` f ripheral portion-28, the serrations of the ange extending in the straps 12 as shown in Fig. 4. Rivets 29 extend through the members 27 and through the straps, con veyer and body portion I5 of the buckle slat. The path of the strap through the buckle is shown in the section in Fig. l and as illustrated therein the strap is passed around the engaging and supporting portion 19 over the pivoted tongue 20 and rearwardly through the slot 23. The pivoted tongue is provided on its front edge with a series 'of teeth- 30 which project into ythe strap land firmly secureit in adjusted position.

From the above description it will be seen that by providing a slat having the buckles formed thereon, in the place of one ot the ordinary slats of conveyer, the space on the conveyer is conserved andthe buckles are always in correct alinement witheach other. y v While I have shown my invention in connection with a quadrantal conveyer, it should be ot course understood that the buckle slat may be used on any conveyer where its use would be desirable.

In disclosing my invention I have illustrated and described one embodiment thereof, but it should be understood that the invention is capable of modiiication, and that modifications may be employed without departing from the spiritl and scope o1 the invention as expressed by the following claims.

1. A slat for conveyers provided with a strap engaging portion, said slat having a buckle member pivotally carried to one side of and coacting with said portion; y

2. A slat for conveyers having a series ot buckle tongues pivoted thereto, means formed on said slat adjacent the front ends of said tongues for supporting and engaging a plurality of straps, and means carried by said slat for receiving and guiding the free ends of saidv straps.

3. A slat vtor conveyershaving a horizontal body port-ions and a continuous vertical web portion, and a buckle tongue pivot-ally supported adjacent said portion.

4l. A slat for conveyers having a horizontal body portion Aand a substantially vertical web portion, a buckle tongue pivotally carried intermediate said portions, and means carried by one of said portions and engaging the other for pivotally securing said tongue to said slat.

5. A slat for conveyers having a horizontal body portion and a vertical web portion extending throughout the length of the slat, a tongue pivoted to said slat, said slat having a slot in said horizontal portion and in said vertical position and positioned in alinement with the free end of said tongue when said tongue is in its operative position.

6. A slat for conveyers having a horizontal body portion and a vertical web portion and a tongue pivoted to said slat, said horizontalA portion having a slot disposed adjacent the free end of said tongue when said tongue is in operative position, and said vertical web having a slot disposed in alinement with the slot in said horizontal portion.

7. A slat for conveyers having a plurality of angularly disposed port-ions, a. tongue pivoted to said slat, said angularly disposed portions having slots disposed in alinement with the free end of said tongue.

8. A slat for conveyers having a substantially horizontal body portion and a substantially vertical web portion said horizontal portion having an upturned strap engaging portion, and a tongue pivoted to said slat at the junction of Asaid horizontal portion with said vertical portion 'for cooperating with said upturned'portion.

In testimony whereof I afIiX my signature.
